It can't find the installation, so you have apparently put them in the wrong place.
If there some reason you don't deploy the files directly to the web server? If they won't give you http access (many won't), then can they give you ftp access to that specific folder? Then you can publish to ftp://(etc), and have the http address as the installation url.
Which version of VS are you using, 2005 or 2008?
